I live in Boynton Beach, FL and I recently assisted RU4ME Pet Rescue, Inc, a 100% volunteer animal rescue organization, with getting set up for a Bitcoin merchant account through Elizabeth Ploshay at Bitpay. This organization runs adoption campaigns out of the Boynton Beach, FL PetSmart each weekend and they have a group of incredible volunteers who house the animals during the week. They are in need of funds to pay back vet bills as vet bills make up the vast majority of their monthly expenses. They are the type of organization that would appreciate even the smallest donation and one of the great features of Bitcoin is that it makes sense for micro payments.
Here are some helpful links. I realize there are many very worthy charities on this forum. If anyone has the ability to donate even a small amount to these guys, I know it would be put to good use.
